Building a deck in Eastham
Eastham is the gateway to the Outer Cape and home to the Salt Pond Visitor Center of the Cape Cod National Seashore.
Eastham meets Cape Cod Bay on the west and the Atlantic and Nauset Marsh on the east. Close to the bay, Nauset Marsh, and the ocean, a deck takes more wind, sun, and salt than one inland, so we use corrosion-resistant hardware and low-maintenance boards where the location calls for it, and we check whether the lot is in a FEMA flood zone before we size the footings.
Bay-side lots in Eastham take the full afternoon sun and the wind off Cape Cod Bay, so heat, fading, and solid railings all factor into the material choice.
Part of Eastham lies inside the Cape Cod National Seashore, where the town’s zoning has a separate Seashore district with its own limits on new structures and expansions. If your lot is in it, we confirm what the bylaw allows before we design.
Many Eastham houses are summer homes, which makes fall and winter a good time to build: the deck can be permitted, framed, and finished before you open the house in spring.

“I’ve worked with Joe and his team on several projects and the workmanship is consistently excellent. Their attention to detail and the ease of communication is second to none. Highly recommended.”

Deck Builder in Eastham: FAQ
Do I need a permit for a deck in Eastham?
Yes, in most cases. A new or rebuilt deck needs a building permit from the Eastham Building Department. If the lot is near a wetland, dune, or the shore, the Eastham Conservation Commission reviews it too. We handle the paperwork.
Do you build decks in Eastham and North Eastham?
Yes. We build and replace decks all over Eastham, including Eastham and North Eastham. Our base in South Yarmouth is about 19 miles away.
What decking holds up best in Eastham?
On a lot close to the bay, Nauset Marsh, and the ocean, composite or PVC boards with stainless or hot-dip galvanized hardware are the low-maintenance choice. Farther from the water, cedar and pressure-treated wood also work well if you are willing to clean and stain them every few years.
Can you replace an old deck in Eastham instead of building a new one?
Yes. We remove the old deck, inspect the ledger, posts, and footings, and rebuild on a sound structure. Reusing the footings is possible when they are in good shape and meet current code.
